Mohanam is a rāga in Carnatic music (musical scale of South Indian classical music). It is an audava rāga (or owdava rāga, meaning pentatonic scale). It is a janya rāga (derived scale), as it does not have all the seven swaras (musical notes).

Mohanam is a symmetric rāga that does not contain madhyamam or nishādham. It is a symmetric pentatonic scale (audava-audava raga[1][2] in Carnatic music classification - audava meaning 'of 5'). Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):

One of the first scales employed by the ancient Tamils was the Mullaippann (3BCE), a pentatonic scale composed of the notes sa ri ga pa da equivalent to C, D, E, G and A in the western notations. These fully harmonic scales, constitutes the raga Mohanam in the Carnatic music style.

The geethamVaravina mrithupani is one of the first short songs taught to beginners in Carnatic music. Ninnukori composed by Poochi Srinivasa Iyengar is a popular Varnam in this scale. Here are some popular kritis composed in Mohanam.
